Fig. 2. Synthesis and characterization of MOC and corresponding host-guest complexes.

A Synthesis of MOC-OTf from L1 and [Pd(MeCN)4][OTf]2 in DMSO. B Chemical structures of the three guests used in this study: tetrabutylammonium salts of hydrogen sulfate (HSO4), nitrate (NO3), and 2,6-diaminoanthraquinone (DAQ). C Partial 1H NMR spectra of L1, MOC-OTf, HSO4⊂MOC, NO3⊂MOC, and DAQ⊂MOC for 1 equiv. of guests added per cage (full spectra are shown in Supplementary Fig. 25–28). Distinct down-field peak shifts relative to L1 indicate successful MOC formation and subsequent guest-binding within the MOC cavity.
